The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

The temperature coefficient of an RTD (resistance-temperature-detector)element is positive. Most stable, linear, and repeatableRTDs are of platinum-metal construction. You can usethe constant 0.00385Ω ...

The RTDM12 Series of RTD temperature sensors have a molded (IP67) four-pin connector with M12 male thread. With a fast response time, the sensor is ideal for pressure-vessel applications, pressurized ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...

Adafruit has today announced the availability of a new PT1000 RTD Temperature Sensor Amplifier MAX31865, which is now available to purchase directly from the online Adafruit electronics store priced ...

Thermocouples function on the principle of the Seebeck effect, which states that two dissimilar metals combined at two junctions produce an electromotive force, or EMF, at the junctions. The metals ...

This article discusses the history and design challenges for designing a resistance temperature detector (RTD)-based temperature measurementsystem. It also covers RTD selection and configuration trade ...

Before running a formal test with multiple resistance temperature detector (RTD) sensors, it is often necessary to calibrate and debug a data-acquisition system to verify basic functionality. The ...

Temperature transmitters are employed to transmit a signal from a temperature sensor, such as a RTD or thermocouple, to a control or measurement device. These temperature transmitters amplify and ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...
